Aluminum Sulfate, identified by its chemical formula Al2(SO4)3 and CAS number 10043-01-3, is a workhorse chemical in the water treatment industry. Its widespread adoption as an effective water purification chemical stems from its unique chemical properties that facilitate the removal of impurities. NINGBO INNO PHARMCHEM CO.,LTD. is a key supplier of this vital compound, providing insights into the science behind its performance.

The effectiveness of Aluminum Sulfate in aluminum sulfate water treatment lies in its hydrolysis reaction in water. When added to water, it dissociates and reacts with water molecules, undergoing a series of reactions that ultimately produce aluminum hydroxide, Al(OH)3. This process can be simplified as follows: Al2(SO4)3 + 6H2O → 2Al(OH)3 + 3H2SO4. The aluminum hydroxide formed is a gelatinous precipitate that exhibits a positive charge.

The impurities commonly found in raw water, such as suspended solids, colloidal particles, and organic matter, typically carry a negative charge. The positively charged aluminum hydroxide flocs attract these negatively charged particles through electrostatic attraction. This neutralization of charges causes the fine, dispersed particles to aggregate, forming larger, heavier clumps known as flocs. This is the core principle of flocculation – transforming tiny, unfilterable particles into manageable aggregates.

Once these flocs are formed, they are easily removed from the water through sedimentation (allowing them to settle at the bottom) and filtration (passing the water through filters). This dual action of charge neutralization and physical entrapment makes Aluminum Sulfate a highly efficient clarifier. NINGBO INNO PHARMCHEM CO.,LTD. ensures that its high purity aluminum sulfate is optimally formulated to maximize this chemical reaction, providing consistent and reliable results for all water treatment needs. When considering the aluminum sulfate price, the efficiency and effectiveness of this chemical justify its widespread use.
